The invention relates tol preserving caps and closures. v

The main object of the invention is to provide a practical glass tumbler-cap and closure. This and other objects are attained by the invention, vone form of lwhich is herein described an-d illustrated by the accompanying drawings. Y

Fig. 1 is a cross section on `the line 1-1, Figure 3, of the tumbler, cover and fastener. Fig. 2 is a cross section of the same on the line 2 2, Figure 3.

Fig. 3 is a plan view of the and fastener.

Figs. 4, 5, 6 and 7 are detail views of fastener parts which are fully described herein. The tumbler 3, a receptacle usually in the tumbler, cover form of the frustum of a cone, and theV cap 4 are preferably made of glass. The upper part of the cap is provided with -a border 5 which surrounds and forms a concavity 6 adapted to contain operating parts of the fastener. The lowerpart of the cap is provided with a wedge-shaped projection 7 which has a rib or part thereon 8 adapted to support and hold a gasket 9. lThe form of the support for the gasket is substantially symmetrical to the interior part of the mouth of the tumbler, that is to say to the rim of the tumbler 10 and to the surface contiguous lthereto 11;

The fastener may conveniently comprise,

the strap 12, a flexible connecting` band 13 oted to the aforesaid strap at 15 and comprises lips 16 and 17 conveniently formed by bending the metal of ywhich it is made' (see Figure 4) on thelines`18 and 19, and so proportioned that the distance 2O (see Fig. 1) exceeds the distance 2l by the desired movement of the cap to the tumbler y when sealing. The pivoted position of the lever aforesaid is maintained by the binding plate 22 (see Fig. 5) g the division 23 being bent or stamped to lit the strap. The edges 24 and 25 are turned -under the forward edges of the lever 26 and 27 (see Fig. 4), and the edge 28 isv bent ar-ound the rear edge 29 of the lever. The metal of which the conneet-ing band aforesaid is made (see Fig. 7

may be bent on the line SO'and the side parts may be curved as at 31 the tumbler.

The latter is pivf to fitl the surface of' In operation, the cap is put on the tum-Q bler with the pivoted lever placed in theconjeavifysrottend, are 'with uit later musi .to theY` axis of the tumbler,"- then, after,` the strap has been swung over the edge 32 of the tumbler and the compensatingiiexible band creases, from 82 to maximum at 34.V These facts together with the flexibility of the conis advanced to the position shown in Fig. 1,

necting band, which adjusts to the circular bottom of the tumbler in passing, produce the desired taut condition of the strap when swung to the position shown in Fig. 1.

The downward pressure ofthe cap and gasket on the rim of thetumbler, owing to the'construction and operation described, re-

solves `partly, into lateral pressure on the interior surface contiguous tothe rim of the tumbler. p

'This may be practically and visibly illus# trated and observedin operating the con-v structions shown in Figs. 1, 2, and 3.

Through the clear glass Vcap and tumbler the kgasket will be seen to be vjammed outwardly or laterallyagainst the interior sur' well as downward face of the tumbler as upon the rim. Y

f Thus slightvariations in diameter aswell as in `rim arev compensated, and the seal is made over the interior surface as well as over the rim ofthe tumbler.

Expansion of the gasket under internal pressure in process cannot injure the seal.

' Gaskets can easily be ycut from a tube of correct size and thickness without loss of material. The resulting gaskets will be like ordinary rubber bands, that Ais to say likebands with edges of equal length as contra- Y distinguished from circular gaskets molded or cut from flat sheets. `Material of an inch thick and 1/3 of an inch wide will give i satisfactory results.

Owing to the form of support described,

gaskets may be used in astretchedconolition as well asin exact lit; thereforejthe gaskets mav be'sterilized and used more than once. A When the cap and tumbler'are closed, the

fastener does lnot interfere with packing, v11o shipping or storing. Y y
